  • Abstract
    We demonstrate integrated optical ring resonators as time-resolved sensors with 3.2×10−5 refractive index unit sensitivity embedded in microfluidic channels. Furthermore, we report the chip-scale detection of segmented flow with different liquid-film thicknesses and capillary numbers.
